Dead Power Seat Recliner
 

I just purchased a 2001 Boxster S... wonderfully maintained by my later brother.

I've discovered that the seatback on the right seat will not recline forward or back when activating the switch on the side of the bolster. No clicks, no grunts, no nothing... dead.

I checked the following usual suspects:
[] fuse is good;
[] pulled the switch and I have 12V on red power feed wire (input power good);
[] 12V appears on grey/ striped wires when moving switch between forward and back (switch is good)
[] 12V appears on grey/ striped wires after the first connector under the seat (first connector is good).
[] Heated seat does work, so is I assume I have a good ground...?

It appears that either the wiring/connector on the way to the motor is bad, I have a bad ground, or the motor itself is toast.

To continue troubleshooting, I need to get to the motor that lives inside the seatback. How do I access it? There is a large, plastic cover on the back of the seat and I suspect that needs to be removed to uncover the motor, but I can't figure out the magic steps to remove it!

Help!
